That made the series 3-1, and it was left to McEnroe to finish off the series against Leconte, the brilliant but erratic 19-year-old left-hander.

"I feel more responsibility playing Davis Cup now than I did when I started," McEnroe said, "because I have to carry the team a little bit" . . .

Martina Navratilova, the world's top woman player, lost a set for the first time since the U.S. Open, but went on to defeat Evonne Goolagong, 6-0, 3-6, 6-1, in the final of the New South Wales Open in Sydney, Australia.

The victory was Navratilova's 14th in 16 tournaments this year and the first prize of $22,000 brought her year's winnings to $680,000 . . .
